One of the worst kinds of posers. These people pose as hardcore fans for bands, usually to look sophisticated or unique, or cool. But don't actually like the music for the sound, only for how they think it makes them look. Hardcore fan posers usually do memorize songs of the band, just so that they can look like real fans. Hardcore fan posers insult people when they say another band is higher in a certain field then that band. It is because they like the label of the band and it insults them to see the band they feel sophisticated/cool/etc listening to, being insulted. When someone says that one member of one band is better than a member of the band they are posing as a hardcore fan of, they will just retaliate by saying that the band they pose as a hardcore fan of is better, even though the other person didn't necessarily say that.

person: The Mars Volta is more experimental than Pink Floyd.

hardcorefanposer: SHUT THE FUCK UP! PINK FLOYD IS A BETTER BAND THAN THAT BAND! THE MARS VOLTA SUCKS!

person: Stfu, I like Pink Floyd, you're such a hardcore fan poser. I didn't say they were better, now just listen to The Mars Volta and face the fact that they are more experimental.

hardcorefanposer: SHUT UP! YOU'RE GAY!

person: Do you even know how Pink Floyd got their name?

hardcorefanposer: They thought it up randomly.

person: uh no, they took the first names of two blues artists: Pink Anderson, and Floyd Council.
